Abstract

The distal end of a flexible tip epidural catheter is stiffened by the insertion of a stress oriented plastic tubular section into the end of the interior of the catheter removed from a terminal flexible tip and then expanded into contact with the wall of the interior of the catheter interior to stiffen a section approximately the length of an epidural needle in which it is to be used.
